Abstract
The invention relates to a head-up display device for representing information in a field of view of an observer. The head-up display device comprises at least one projection device, a deflection device which comprises at least one deflection element at which incident light beams are deflected, a sensor device, and a control device. The sensor device is used for detecting data of at least one test beam which is incident on the deflection device. The control device is used for determining at least one aberration caused by the deflection device and for determining at least one correction signal in real time.
